Assembly, comprising an element (2) defining a lying or support surface, such as a foam layer forming a core of a mattress, and a device (3) associated with the element (2) for adapting the form of the lying or support surface in waves, wherein the device (2) comprises at least one selectively expandable and/or compressible body. The body (3) is further embedded in or arranged under a part of the element (2) which is lower-lying during use and has above it at least a greater part of the thickness of the element (2). The body (3) acts on a wave part of the element (2) so as to selectively bring about waves in the lying or support surface, which wave part is connected via a hinged configuration to other parts of the element (2).
